Abstract

A mobile device, a controlling method thereof, an image display apparatus, and a controlling method thereof are provided. The mobile device includes: a user interface (UI) configured to receive a user command to control the image display apparatus; a communication interface configured to provide a service according to the user command through an access point (AP) to which the image display apparatus is connected, and perform a direct connection operation with the image display apparatus in response to the service being provided; and a controller configured to control the communication interface to hand the service over to a direct channel connected to the image display apparatus in response to the direct connection operation being completed.

Claims

1. A mobile device to control an image display apparatus, the mobile device comprising:

a user interface (UI) unit configured to receive a user command to control the image display apparatus;

a communication interface unit configured to provide a service according to the user command through an access point (AP) to which the image display apparatus is connected, and perform a direct connection operation with the image display apparatus when the service is provided; and

a controller configured to control the communication interface unit to hand the service over to a direct channel connected to the image display apparatus when the direct connection operation is completed.

2. The mobile device of claim 1, wherein the UI unit comprises a display unit configured to receive the user command,

wherein the controller controls the display unit to perform a screen mirroring operation of the mobile device through the image display apparatus.

3. The mobile device of claim 1, wherein the communication interface unit comprises:

a wireless local area network (WLAN) module configured to perform a WLAN communication with the AP; and

a Wi-Fi direct module configured to perform a Wi-Fi direct communication with the image display apparatus.

4. The mobile device of claim 3, wherein the communication interface unit further comprises:

a switching unit configured to select at least one of the WLAN module and the Wi-Fi direct module under control of the controller.

5. The mobile device of claim 1, wherein the controller communicates with the AP to determine whether the image display apparatus is connected to the AP, provides the service when it is determined that the image display apparatus is connected to the AP, determines whether the direct connection operation is completed, and performs the handover when it is determined that the direct operation is completed.

6. An image display apparatus controlled by a mobile device, the image display apparatus comprising:

a communication interface unit configured to receive a service through an AP, to which the image display apparatus is connected, under control of the mobile device and to perform a direct connection operation with the mobile device when the service is received; and

a controller configured to control the communication interface unit to receive the service through a direct channel connected to the mobile device according to a handover of the mobile device when the direct connection operation is completed.

7. The image display apparatus of claim 6, further comprising:

a display unit configured to display an image signal related to the service,

wherein the controller controls the display unit to perform a screen mirroring operation of the mobile device through the image display apparatus.

8. The image display apparatus of claim 6, wherein the communication interface unit comprises:

a WLAN module configured to perform a WLAN communication with the AP; and

a Wi-Fi direct module configured to perform a Wi-Fi direct communication with the mobile device.

9. The image display apparatus of claim 6, wherein the communication interface unit further comprises:

a switching unit configured to select at least one of the WLAN module and the Wi-Fi direct module under control of the controller.

10. A method of controlling a mobile device which controls an image display apparatus, the method comprising:

receiving a user command to control the image display apparatus;

providing a service to the image display apparatus through an AP, to which the image display apparatus is connected, according to the user command;

performing a direct connection operation with the image display apparatus when the service is provided; and

performing a handover to a direct channel connected to the image display apparatus to continuously provide the service when the direct connection operation is completed.

11. The method of claim 10, wherein the user command comprises a screen touch type command and a command to control the image display apparatus to perform a screen mirroring operation of the mobile device.

12. The method of claim 10, wherein the AP performs a WLAN communication with the mobile device and the image display apparatus, and the mobile device performs a Wi-Fi direct communication with the image display apparatus.

13. The method of claim 10, wherein the providing of the service to the image display apparatus comprises:

performing a communication with the AP to determine whether the image display apparatus is connected to the AP,

wherein the service is provided according to the determination result.

14. The method of claim 10, wherein the continuously providing of the service comprises:

determining whether the direct connection operation is completed,

wherein the handover is performed according to the determination result.

15. A method of controlling an image display apparatus by a mobile device, the method comprising:

receiving a service through an AP, to which the image display apparatus is connected, under control of the mobile device;

performing a direct connection operation with the mobile device when the service is received; and

continuously receiving the service through a direct channel connected to the mobile device according to a handover of the mobile device when the direct connection operation is completed.

16. The method of claim 15, further comprising:

displaying an image signal related to the service on a screen,

wherein the control is controlling the image display apparatus to perform a screen mirroring operation of the mobile device.

17. The method of claim 15, wherein the AP performs a WLAN communication with the mobile device and the image display apparatus, and the image display apparatus performs a Wi-Fi direct communication with the mobile device.
